Get matched with top deck cleaning pros in Santa Clara, UT

The average cost to professionally clean or pressure wash a deck is around $150, with prices typically ranging from $100 to $600. Several factors influence the final price, including the deck's size, material, condition, and how long it has been since its last cleaning. For a smaller deck of about 300 square feet, you might pay around $100. For a larger deck of 1,000 square feet or more, the cost could be closer to $300 to $400. Decks that are very dirty or haven't been cleaned in years may require more time and special detergents, which will increase the price. The deck's material also plays a role. Wood decks often cost more to clean because they require a gentle power washing technique to avoid damage. Composite decks are typically less expensive to clean, and cleaning a metal deck may cost around $100.

PVC decking can get slippery when wet because it’s made from plastic. However, composite and wood decking can also be slippery when wet. It’s best to wear shoes with grippy soles when walking on a wet deck, no matter the material, and to be extra cautious not to slip and fall down.

It’s important to make sure the wood on a new deck is properly seasoned. Seasoning a deck is simple: Once you build it (or have a pro do so), just leave it alone so it can acclimate to the environment. If you don’t give the deck proper seasoning time before staining, the stain can lock in any lingering moisture and cause mold, rot, and other moisture issues down the road. Give the wood at least four to eight weeks to season before you stain.

Building a deck without a permit could lead to fines for both the homeowner and the contractor. The exact penalties will depend on your state and municipal building laws. You might also be required to remove the deck and apply for a permit before you can build another. While it might be tempting to skip the permit to save a few bucks, it’ll cost you much more if you’re caught.
